Most of us would know exactly what the phrases 'slug bug', 'punch bug' or 'punch beetle' mean. They're normally associated with sudden shrieks and a punch in the arm. I'm talking about that old car game that created hours of fun for any kid on a boring car journey. The object of the game was to be the first to spot a Volkswagen Beetle, call out 'slug bug' and punch the other player in the arm. Using Google Street View Imagery via the Google Maps API, Volkswagen has brought this much-loved, old tradition into the modern digital world. Now anyone, anywhere can play the game without ever having to be in a car.
